To ft/Z whom zit may concern;

Be it. known that we, EDWARD R. POST and EDWARD S. GRISE, citizens of the United States, residing at Ottawa, in the county of Putnam and State of Ohio, have invented certain new and useful Improvements in Nut- Locks; and we do declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in n ut-locks of that class in which is employed a spring-fastener engaging in depressions or the like in the nut and washer to prevent its turning.

The present invention has for its object, among others,to provide an improved nut-lock of this class which shall be simple,yet eicient, and in which is employed a washer, adapted to he held in or to the fish-plate or other part, and a nut screwed upon the bolt and the two held against turning by a spring-bow fastener engaging in corresponding openings in the adjacent faces of the washer and nut. By this construction the washer can be readily applied upon the bolt and the nut then screwed up, avoiding the necessity of screwing up the one part, as heretofore.

-Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined b the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the let- -ters of reference marked thereon, form a part of this specification, and in which-` Figure l isa vertical transverse section showing the application of the invention toa railway-rail. Fig. 2 is an enlarged view of the bolt, nut, washer, and locking-bow, the nut and washer being shown in section. Fig. 3 is a View similar to Fig. 2, showing a form of Washer adapted for use with wood. Fig 4 is a face View of the nut looking at the inner face thereof. Fig. 5 is a sectional View taken on line a: of Fig. 2 looking in the direction of the arrow. Fig. 6 is a side elevation of the two forms of washers used.

Like letters of reference indicate like parts throughout the several views.

Referring now to the details of the drawings by letter, A designates a bolt provided with screw-threads a and a shoulder a'.

Bis a washeradapted to be slipped upon the holt and to engage the said shoulder to limit its inward movement,as Will be readily underbore, so it may be easily slipped upon theI bolt without the necessity of screwing the same thereon, and this washer' is adapted to beheld immovably to the part against which it oontacts. When the improvement is to be used in connection with metallic parts-as, for instance, when employed in connection with railway-rails, in which case the washer will be held to the iish-plate-it is provided with a lug or projection b, as shown in Figs. land 2, which is designed to engage in a hole or depression C in the fish-plate, so that when the said lug or projection is engaged in said hole or depression the washer is held immovably as regards the fish-plate. There may he more than one of these lugs or projections ii' desired, and the said lug or projection may be of any desired shape in cross-section.

When adapted for use in connection with wooden parts, the Washer is formed with one or more points D, as seen in Fig. 3, which are designed to be pressed into the wood, where they serve the same function as the lug or projection in the form just described.

E is a nut. It, as well as the washer, may he of any desired shape about its periphery, preferably six-sided, although this is not essential. lt is adapted to be screwed upon t-he bolt and is provided upon its inner face with a series of depressions E, as shown,

point more or less removed or distant from clearly in the drawings, so that the ends of the locking device when in place cannot contact with the threads of the bolt. The adjacent face of the washer is provided with a series of like depressions G, as shown, and when the Washer and nut are in position the openings therein will be coincident to form sockets in which are received the ends of the spring locking-bow now to be described. This bow Ulis in the form of, a bow or yoke, as

which extend from the outer periphery to a the bore or passage through the nut, as seen?" stood. This washer has a smooth Unthreaded ...awww

show'n,'and its ends extend inward to forni the projections or points I, as seen clearly in Fig. 2.

The operation will be apparent' from the foregoing description when taken in connection with the annexed drawings. W'hen using the form of washer seen in Figs. 1 and 2, the washer is placed in position with its lug or projection in the opening in the fish-plate, and then the nut is screwed hoine. When in the desired position, the spring-how is ap plied, the ends heing sprung apart, so that projections thereof will enter the opposite openings or cavities in the washer or nut, when the resiliency of the bow will cause the saine projections to springr into the said openings orcavil ies, and by this means the washer and nut will be locked, so that the nnt cannot work loose. When using the form of washer with points, the screwing up of the nut. will tend to force the pointsinto the wood, and when the fastener is applied in -the same manner as above the nut will he held against retrograde movement. The spring of the how will permit, of the movements occasioned by the vibrations or shock assing trains and will compensate therefor;v The nut may be removed by simply springing one end of the how out of the opening in which it has lbeen engaged, when the bow. may he removed and the nut free to be unserewed, as will be readily understood. What we claim as new s- 1. The combination with a bolt, of an unthreaedvv'ash'er thereon, means for preventvent its turning and a spring-fastener en-V gaged in the coi ieident openings in the nut and washer, and for the purpose specified.

3. The combination with a bolt, of an unthreaded washer thereon, means for locking said washer against revolution, a nnt engaging the threads of said bolt, said washer and nut having upon their adjacent faces correp o n i p dingoenings extending toward the oener, an( a spring-bow having projections on its ends engaging in the openings in the nut and washer upon diametrically-opp'osite sides thereof, to lock them against movement, substantially as set l'orth.

In testimony whereof we affix our signatures in presence of two witnesses.
